Probably not the film you're thinking of, but there was a similar scene in
Caligula (1979). Caligula has ordered the Senators' wives to prostitute themselves to raise money, and upon viewing one particularly unattractive wife, quips to her husband that she's scaring customers away.
As I said, probably not the movie you had in mind, but this relatively famous scene might have 'inspired' the scene in the movie you're looking for.
sorry, I Imdb the Movie connections for Caligula and didnt find what I'm looking for (it doesnt mean that the scene isnt a copy it just means that its not listed)
I do remember faintly it was one of those crime action films. And the fat strippers were so out of place that it was funny. Its not a Chuck Norris or a Charles Bronson action film but this story was quite similar (maybe too similar since I cannot remember the rest of the film)
